Just a quick update for anyone who is curious,
The memtest86 ran for just under 6 hours, made 5 passes at the memory,
and didn't find a single error!  Strange that Win98 (through 3 different
installs) exhibits regular lockups with the additional memory in, but
yet doesn't ever lock without the memory in it.

However, the good news is, since I switched this laptop over to linux,
it has been running quite stable now with the extra memory in it.  Hmm,
strange, but I'll take it.
